User questions & answers

Question:	If I have a Capacitor do I need a second battery
Answer:	No need. This is not a "fashion item", it is a reflector. It's sole purpose it to push light into the shadows, not give your set-up some sartorial elegance.
Question:	Does it come with speaker wire
Answer:	The case is 9 1/4" in diameter, but it has a "hook", so you can hang it on you belt.
Question:	The led doesn’t stay on is that a problem ? It reads when I first start the car but a minute later it shuts off, it is full I believe but no display
Answer:	I don't know the exact measurement, but it's about the size of a frisbee.
Question:	Is this ofc (oxygen free copper) cable
Answer:	they are reflectors use them on an angle

User questions & answers

Question:	Does this have a remote wire input
Answer:	The correct size is 3 1/8" diameter.
Question:	will this work with 24v input
Answer:	The black side maybe it's a no for the white part as it's mainly used to diffuse the sun.
Question:	Do i have to use the negative from the battery or can I use the negative I have ran through the trunk
Answer:	I have the two handle, larger model. The Frame is diffused when used by itself. There is a single cover that "sandwiches" the diffused frame. This cover is reversible, providing 4 different surfaces. But whatever you choose, has only two sides. You don't have every possible combination in one second, by turning the reflector over. I think this is what you want to know...Thus, on the larger model; White on one side, turn the reflector over; Gold. This is the most popular portrait combo. Take the slipcover off, and turn inside out. Now you have Black / Silver. That's the scoops Bud!
Question:	I have pioneer a1686r 350w & a6996r 650w speakers, joying front unit, also want to buy a subwoofer and amp. should i get one of these caps
Answer:	No,It's white&gold or silver&black

Rockville RXC4D 4 Farad/12 Volt Digital Power Capacitor+RWK41 4 AWG Amp Wire Kit

Today’s car audio amplifiers need huge amounts of current. Often a vehicle’s electrical system is unable to provide it. With your car’s air conditioning running, the factory electrical charging system may already be operating at only 70% of full capacity. When a bass note hits or when playing your system very loudly, there may not be enough electrical energy to power your amplification system properly causing your music to sound strained and distorted. Rockville capacitors are designed to store enough electrical current and to release this energy extremely fast due to their superior design and low internal resistance. In addition, as quick as your amplifier needs a new current surge, your Rockville capacitor will provide it.

Product description

A stiffening capacitor is an extremely large value electrolytic capacitor. Capacitors have the ability (capacity) to store a charge on their "plates". The larger the capacitance, measured in units of Farad, the greater the charge a capacitor can store for a given voltage. Most automotive capacitors can store a charge at 10 to 20 volts and are rated from about .5 Farad up to 50.0 Farad or even more. Capacitors have an extremely low internal resistance to current flow, much lower than that of a battery. Capacitors can therefore charge and discharge power much faster than a battery can.

User questions & answers

Question:	is this for voice and bass
Answer:	I would opt for matching voltages to insure component will degrade at a similar pace
Question:	How u charge this thing
Answer:	No. The capacitor gets its power from the battery. If I'm not mistaken
Question:	I have 2 2000watt monos but at 4 ohms its 500 rms ...will this be able to handle that
Answer:	Ignore the "spot in the morgue". Yes, it can deliver a crazy amount of power @ 14.4V (nominal), but at 14.4V, the current has a very high resistance to flow through your body, and you'd likely not feel it unless you're sweaty and haven't bathed in a few days. Aside from that, these aren't designed for short-circuit use, so your mileage may vary. It might work great for a few welds and pop. It might work great for thousands of welds. Who knows? If you try it, do let me know, I could use a spot welder.
Question:	What does a capacitor do
Answer:	Im not too sure but i have 3000 watts on my own and it can take more so i don't know exactly how much it can handle

User questions & answers

Question:	Do I really need this when I'm Not having voltage drops but instead amperage lack
Answer:	Yes you can use one big one. You can wire this in between the amps and the car battery. It will pull the power from this before getting to the battery. It doesn’t matter how many amps are hooked up. It depends on how much power you’re pulling. So just get one to match the power being pulled and this acts like a quick response team for the power needed.
Question:	I have a old school quantum audio qb2000d powering 2 quantum q1500/10s. 2 batts. still crazy vd and dimming lights. will this work out for me
Answer:	Hello, The CAP8 only flashes when it is charging. Thank you, Boss Audio
Question:	Capacitors are known for cleaning mids and highs in your car stereo. Does it mean this can eliminate some degree of distortion or shrill treble
Answer:	The capacitor doesn't come with a distribution block. The rule of thumb is to put in 1 Farad of capacitance for every 1,000 watts RMS of total system power so yeah you'll have plenty of power.
Question:	I need a little more I have this cap I love it but still lights flicker
Answer:	Hello, The CAP8 comes with a 1 Watt/51 ohm Resistor and mounting hardware.

True 1.0 Farad 20V Capacitor with Digital Read-out, Built-in Distribution Block

Keep your lights bright and your system bumpin'! The XCAP1F True 1.0 Farad Capacitor will deliver. It has been tested to be a true 1-farad capacitor, unlike nearly all of the competition which is really 0.2 farad to 0.8 farads. Being that it is a true 1-farad capacitor you know you're getting optimum performance. You will notice improvements in your bass response (SPL), increase the peak power of your amp, and help stabilize the voltage of your system.

The XCAP1F capacitor owes its true 1.0-farad rating to the fact that has more electrical conductors as well as a greater amount of dielectric than its competitors that claim a 1.0-farad rating. This true 1.0 rating allows it to easily handle any stereo system with up to 1200 watts of power output.

As with all NVX products, the XCAP1F true 1.0 Farad Capacitor continues the company's goals of engineering excellence and amazing prices.

Product description

A stiffening capacitor is an extremely large value electrolytic capacitor. Capacitors have the ability (capacity) to store a charge on their "plates". The larger the capacitance, measured in units of Farad, the greater the charge a capacitor can store for a given voltage. Most automotive capacitors can store a charge at 10 to 20 volts and are rated from about .5 Farad up to 50.0 Farad or even more. Capacitors have an extremely low internal resistance to current flow, much lower than that of a battery. Capacitors can therefore charge and discharge power much faster than a battery can.

This power "reservoir" in the capacitor only works to a point. If the power draw from the amplifier or multiple amplifiers demands so much power that the alternator can't bring the charging system and capacitor back up between bass transients, then reduced bass response and flickering lights will again occur. Adding more capacitance may help, but an alternator with a higher current rating would be a better solution.

Wherever you're on the road with ATV, motorcycle, snowmobile and any vehicle, IT is extremely reliable and long last Stiffening Power Capacitor you can rely on.
